Abstract

PURPOSE:To secure special effects such as fade-in, fade-out, etc. in a blank period by inserting a blank period into the transmission number of a certain channel to change the channel after insertion of the blank period and actuating different VTRs for reproduction before and after said space period. CONSTITUTION:When a transmission number is inserted, the reproduction start time point of a tape cassette 7 of the subsequent transmission number is delayed by an operation of a control means 24 of a computer. Then a corrected transmission list is projected on a monitor picture receiver 14M. A channel to which a blank period is inserted is detected by a channel detecting means 80. Based on this detection data, a detecting means 82 detects the next channel. The detection data of both means 80 and 82 are given to a channel changing means 83, and the channel after a blank period of the channel inserted with a blank period is changed into a channel excepting for both said channels and stored to a memory means 25.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an apparatus for creating a reproduction transmission list for a tape cassette.

BACKGROUND TECHNOLOGY AND PROBLEMS The present applicant previously proposed a tape cassette automatic supply selection and playback device described below. The outline of this device is as follows. A shelf device including a plurality of shelves is provided, and tape cassettes on which video signals are recorded are stored in the plurality of shelves.

A bar code is attached to the back of this tape cassette to indicate identification data related to the contents recorded on the tape. Then, the tape cassettes stored in this shelf device are transported and loaded into a plurality of VTRs by an elevator, and
The tape cassette taken out from the VTR is transported to a shelf device by an elevator and returned to the shelf. This elevator is provided with means for reading bar codes of tape cassettes stored in the shelf device. The reproduced signals from the plurality of VTRs are then selectively sent out by the selective sending means.

Furthermore, a microcomputer is provided, and is connected to the above-mentioned shelf device, a plurality of VTRs, an elevator, a selection sending means, and the like. Further, identification data read from the barcode of the tape cassette stored in the shelf device is stored in the storage means of the microcomputer. Then, the microcomputer controls a plurality of VTRs, elevators, selective sending means, etc., to reproduce and send out the recorded contents of the tape cassettes stored in the shelf device in a predetermined order based on the sending list.

OBJECTS OF THE INVENTION The present invention arranges a plurality of tape cassette reproduction transmission numbers and a switching period of a reproduction device according to a time sequence, and also sequentially assigns different channels to a plurality of tape cassette reproduction transmission numbers before and after the switching period. When a new switching period is inserted between adjacent tape cassette playback and sendout numbers in the playback and sendout list in a device that creates a playback and sendout list for tape cassettes for which a playback device is specified, the overall The order of channels is not changed, the change in the order of channels is partially stopped, and furthermore, by inserting a new switching period, other switching periods that already exist disappear and the special effect cannot be generated. This is an attempt to propose something that has no risk of becoming a problem.

SUMMARY OF THE INVENTION The tape cassette reproduction and transmission list creation device according to the present invention arranges a plurality of tape cassette reproduction and transmission numbers and a switching period of a reproduction device according to a time sequence, and also arranges a plurality of tape cassette reproduction and transmission numbers and a switching period of a plurality of tape cassette reproduction and transmission numbers. A storage means storing data of an original reproduction transmission list in which reproduction apparatuses of different channels are sequentially specified before and after a period, and reproduction transmission of adjacent tape cassettes in the reproduction transmission list stored in the storage means. When a new switching period is inserted between the numbers, channel detection means detects the - channel of the adjacent tape cassette playback transmission number and the next channel, and the detection output of the channel detection means is used. Among the tape cassette playback and transmission numbers belonging to the channel in which the new switching period has been inserted, the channel with the tape cassette playback and transmission number after the new switching period is set to - and other channels. The present invention is characterized in that it has a channel changing means for changing to another different channel, and that the channel changing result of the channel changing means is added to the data of the original reproduction transmission list.

According to the present invention, a plurality of tape cassette playback and transmission numbers and a switching period of a playback device are arranged according to a time sequence, and a plurality of tape cassette playback and transmission numbers are sequentially assigned to playback devices of different channels before and after the switching period. When a new switching period is inserted between adjacent tape cassette playback and sendout numbers in the playback and sendout list in a device that creates a playback and sendout list for tape cassettes in which the playback and sendout list is specified, the overall channel does not change the order of channels, partially stops changing the order of channels, and inserts a new switching period, which causes other switching periods that already exist to disappear, making it impossible to generate special effects. You can get something without fear.

EXAMPLE An example of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows the tape cassette automatic supply selection and playback machine M as a whole. In FIG. 1, one tape cassette automatic supply selection and playback machine M is explained, but in actual use, one In addition to using the tape cassette automatic supply selection and playback machine M of used interchangeably or interchangeably.

In Fig. 1, (1) shows a shelf device, (11) to (
1n) is a plurality of shelves, for example, 40 shelves.

Reference numeral (2) denotes an elevator as an elevating and lowering transportation means, which is driven and controlled by an elevating and lowering drive means (4) and is raised and lowered along a guide (3). This elevator (2) is provided with two shelves (5) and (6), the upper shelf (5).
) is the tape cassette (7) from the shelves (11) to (1n)
(Fig. 2) and return it to its original shelf or pass it to, for example, four VTRs (81 ((8z) to (84)), and the lower shelf (6) T R (8)

This is a shelf for returning to either of 1n). (9), aΦ
are motors that drive actuators (not shown) for moving the tape cassettes (7) on the upper and lower shelves of the elevator (1), respectively.

Further, (12) is a bar code (12) that is provided on the upper shelf (5) and is attached to, for example, the back of the tape cassette (7) as shown in FIG.
11) is a photodetector as a detection means for detecting. A detection signal from this photodetector (12) is supplied to a microcomputer (14) via an A/D converter (13). (14M) and (14K) are a monitor receiver connected to the microcomputer (14) and an auxiliary controller (equipped with a keyboard) capable of being a wired or wireless remote controller.

In addition, indicators (15) ((151) to (15n)) such as LEDs are attached to each side of the shelves (41) to (In), and 5% (15) of this display is based on the microcomputer (14 ), and when the barcode (11) of the tape cassette (7) stored on that shelf is correctly read, the indicator corresponding to that shelf is turned on.

The contents of the identification data based on the barcode (11) attached to the tape cassette (7) include, for example, as shown in FIG. Sending number (story number) b, Title of tape recorded content for 14 characters C Tape playback start time for 18 characters (hours, minutes, seconds, and frames (1/30 seconds)) d, Tape playback time for 6 characters ( hours, minutes, seconds and frames)
It consists of e and a checksum g for one character. There are various types of barcode patterns for one character, but in this example, there are two patterns as shown in Figure 4A.
A 2 of 5 interleaving method is adopted. In other words, a barcode for one character is constructed from three black bars with a width of 1 and two black bars with a width of 3.
The total width of the black bars is 9.

A barcode is also formed by the spacing between these bars, and another barcode for one character is formed from the three own bars with a width of 1 and the two own bars with a width of 3.

Next, we will explain how to read barcodes. For example, consider detecting a barcode consisting of black bars.

The barcode detection signal detected by the detection means (12) in FIG. 1 becomes a sine wave whose period varies depending on the width of the black bar as shown in FIG. 4B. By shaping this waveform, an identification data signal having a time width corresponding to each black bar as shown in FIG. 4C is obtained. 1st to 5th
The pulse width of the data of the 8th black bar is jl+ L3+
j6+ j? +ts, and the pulse width of the data of the own bar during that time is t, t4+te*to. Thus, when a one-character barcode signal is played,
Add up each pulse width tヱ* j3+t5+''T+ts, divide this by 9, multiply it by 1.5 to obtain a threshold value, and compare this with the pulse width of the data corresponding to each black bar. As a result, the thickness of the black bar of the barcode is detected, and the barcode for one character is read.The same applies to the white bar.

First, one to a plurality (n or less) of tape cassettes (n or less) necessary for a certain unit broadcast time are placed on the shelves (11) to (1n).
7) is stored manually.

Then, the barcodes (11) of all the tape cassettes (7) stored in each column are read and stored in the microcomputer (14). This will be explained with reference to Fig. 5. This Fig. 5 shows this barcode (

The functions are shown in blocks. The elevator (2) is provided with the above-mentioned detection means (12) and A/D converter (13), and the detection output of the detection means (12) is supplied to the A/D converter (13) and converted into a digital signal. be converted into The digitized detection signal is then supplied to the time width detection means (16), and the digitized detection signal is counted by the clock signal from the clock signal generator (17) with a sufficiently high frequency. The time width is detected. Then, the threshold value described above is calculated in the threshold calculation means (18). Then, the output of the time width detection means (16) is the comparison means (19?
and is compared with the threshold value from the threshold calculation means (18) to detect data based on the thickness of the black bar (or white bar). This means of comparison (
The output of 19) is sent to the data time width size code conversion means (2

The barcode data obtained from the main control means (24
). Incidentally, this main control means (24) is provided with a storage means (25).

From the main control means (24), a display control means (26) that controls the display on the display (15), and an actuator control that controls an actuator (not shown) for moving the tape cassette in the upper stage of the elevator (2). Means (2
7), the elevator (2) via the lifting drive means (4);
An elevator control means (28) that controls the detection means (28) and a drive control means (29) of the detection means that controls the drive means (plunger) (34) of the detection means (12) that changes the angle of the detection means (12) (described later). A control signal is supplied to each.

In addition, the display control means (26) is a display device (15) ((15
z) to (15n)) to ensure that the barcode (11) is read during the reciprocating movement of the tape cassette (7) on the shelf (5) above the elevator (2); Corresponding display (15) ((151) ~
(15n)) is lit. The actuator control means (27) control the motor (9) which drives the actuator of the upper shelf of the elevator (2).

FIG. 6 shows that when the barcode (11) of the tape cassette (7) described above is detected back and forth by the detection means (12), if the barcode (11) is not detected correctly, the detection means (12) ) to change the angle of the barcode (11
) shows the driving means of the detection means (12) that changes the detection position in the width direction, (7a) is the back of the cassette case of the tape cassette (7), (11') 4J: Barcode (11)
The label is affixed to its back (7a). The detection means (12) is attached to the holder (30) and is rotatable around the central axis (31). and,
A lever (32) is provided extending from the holder (30), and is pivoted clockwise by a spring (33). On the other hand, (34) indicates a plunger, and in a critical state, the plunger (34) is not energized, and the lever (32) is pulled by the spring (33) in the non-energized state of the plunger (34), so that the detection means ( 12) is at the position of the broken line. When the plunger (34) is biased by the control output of the control means (29), the actuator of the plunger (34) moves to the right in the figure, and the lever (34) moves against the elastic force of the spring (33). ) rotates counterclockwise, and the detection means (12) comes to the position shown by the solid line. Thus, the barcode (1
1) at different positions in the width direction, its barcode (11)
can be detected.

Next, the functions of the computer (14) shown in FIG.
This will be explained with reference to the flowchart shown in the figure.

As shown in FIG. 1, the elevator (2) has a shelf (5) thereon in a position where tape cassettes stored in, for example, a shelf (14) of the shelf device (11) can be delivered.Control means When the motor (9) is controlled by the motor (27) and the actuator (not shown) is driven, the tape cassette (7) (not shown) stored in the shelf (14) is moved onto the elevator (2). Move to the shelf (5).

At this time, the barcode (11) is read by the barcode detection means (12). This barcode detection means (
The detection output of 12), that is, the digitized detection output from the A/D converter (13), is supplied to the data width detection means (16), the data width is detected, and the detection output is sent to the width comparison means (19). is supplied to the threshold calculator 9 (
1B). The output of the width comparison means (19) is the data width code conversion means (20) - 2 of 5 code conversion means (2).
1) The barcode data is supplied to the data creation means (23) through the ASCII code conversion means (22) to create barcode data. Furthermore, when the actuator is driven, the barcode (11) is read again when the tape cassette (7) returns from the shelf (5) above the elevator (2) to the second shelf (14), and the tape cassette (7) is read again. Similar signal processing is performed. Then, in the main control means (24), it is determined whether or not the barcode (11) has been read in a reciprocating manner. If it is determined that the barcode (11) has been read in a reciprocating manner, the barcode data is read in a reciprocating manner. It is determined whether the code data has been reliably integrated.

When it is found that the barcode data cannot be read properly, the drive control means (29) of the detection means is controlled to change the angle of the detection means (12) as shown in FIG. By moving the tape cassette (7) from the shelf (14) again to the shelf (5) above the elevator (2) and returning it to the original shelf (14), the barcode (11) is removed.
The reciprocating reading is performed in the same manner as described above at different positions in the width direction.

When it is determined that the barcode has been read as correct data, the display (154) of the shelf opening where the tape cassette (7) was stored is turned on, and the elevator control drive means (4) to start the elevator (2), raise or lower the elevator (2), and stop the elevator at the next shelf. Then, the same operation as described above is performed.

If the barcode is read correctly, the content of the barcode of the tape cassette (7) is stored in the storage means (25) together with the shelf number, and the monitor receiver (14)
Display it on the screen of M). By repeating this, the identification data related to the tape recording contents of all the tape cassettes (7) stored in the shelves (11) to (1n) are read, and this is stored in the storage means (25) along with the shelf number. and can be displayed on the screen of the monitor receiver (14M).

Next, the means (40) for selectively transmitting the reproduced video signals from the VTRs (81) to (84) in the tape cassette automatic supply selection reproduction machine M shown in FIG. 1 will be explained with reference to FIG. . The reproduced video signals from the VTRs (8t) to (84) are selected by the selection means (microcomputer (14) in Figure 1).
) (41) and is separately supplied to any of the output terminals (42^) to (42D). Video signals of channels A to D from output terminals (428) to (42D) are sent to the microcomputer (1
The playback video signal from the selected one VTR is switched by the switching means (having a built-in special effect generator) (43) controlled by the output terminal (4).
3') and is supplied to a broadcasting device (not shown).

Next, a method of selectively transmitting reproduced video signals from a VTR will be explained. First, create a sending list. this is,
ζ may be created using the microcomputer (14) shown in FIG. 1, or may be created separately. This sending list is printed on paper. This transmission list is stored in the storage means (25) of the microcomputer (14) (FIG. 1), and is also read out and displayed on the monitor image fi (14).
M) (Fig. 1) is displayed on the screen.

Items in the transmission list include, for example, ■ transmission number, ■ mode identification number, ■ title, and ■ tape playback start time (
hours, minutes, seconds), ■Tape playback time (hours, minutes, seconds), ■
Tape playback cumulative time (hours, minutes, seconds), ■Tape cassette automatic supply selection and playback machine (indicated by number, etc., if there is only one unit, this item can be omitted), ■Shelf (shelf (11)
~(In) corresponding number), ■Channel (any of A-D), +1 VTR (VTR (8t) ~(
84) corresponding to numbers 1 to 4), etc. Note that the order of the items is arbitrary.

Among the items ■ to [phase] in the sending list, initially, for example, the item ■
Fill in the ~■ columns (some of the other items except ■ can be omitted) with data, and fill in the remaining fields with tape cassettes (
It is filled in with data obtained by considering the data read from the barcode (11) in 7) and data of other items.

Among the items ■ to [phase] in the sending list, the column for the initial item ■ is filled with data, and the remaining columns are filled with data read from the barcode (11) of the tape cassette (7). It is also possible to fill in the information with data obtained by taking into consideration the data of other items.

Between each of the above-mentioned transmission numbers, there is a blank period for playback and transmission, such as when images of objects in the studio (for example, anallancers, performers, etc., chart panels, etc.), live (relay) images, etc. are being broadcast. There are cases. During this blank period, for example, enter rBRBAKJ or rBKJ in the transmission number column of item ■.
is displayed, and its content (title) is displayed in the title column of item ■. Then, each time a blank period is inserted between transmission numbers, the channel is sequentially changed, and the VTR is also changed accordingly. In this way, special effects such as fade-in and fade-out can be generated by inserting a blank period (switching period) of zero time or minute time between transmission numbers. Note that this blank period is also included in the cumulative tape playback time.

For example, when using this tape cassette automatic supply selection and playback machine M for broadcasting news, news shows, advertisements, etc. in a certain time period, the number of tape cassettes (7) required is one tape cassette automatic supply selection and playback. Machine M shelf (11
) to (1n), it is necessary to use a plurality of automatic tape cassette supply/selection playback machines M1 to Mk and distribute the tape cassettes (7) to each of them.

Next, how to sort tape cassettes (7) using the computer (14) will be explained with reference to the functional block diagram of FIG. 9 and the flowchart of FIG. 1O. In Figure 9, (44) is a tape cassette (7
) is shown as a whole. That is, the storage means (25
) is read out and supplied to the blank period position detection means (45), and the data of the transmission number immediately before the blank period is stored in the storage means (25). Then, the data on the position of the blank period stored in the storage means (25) is given to the calculation means (46) for calculating the appropriate number of tape cassettes, and the sending number is set to n (for example, 40) in the appropriate blank period. Blocks of sending numbers, i.e. tape cassettes (
7) Form blocks (groups).

Then, the data of the calculation result of this calculation means (46) is
Sending number and tape cassette automatic supply selection playback machine M1-M
k to the specification means (47), the data of the specification result is stored in the storage means (25), and the data of the specification result is used to automatically select the tape cassette of item (■) on the screen of the monitor receiver (14M). You can fill in the column for the supply selection regenerator.

For example, in the case of spot advertisement broadcasting, it is assumed that there are a total of 1 to 140 °C1 transmission numbers. For example, between transmission numbers 35 and 36, between 66 and 67, between 77 and 78,
It is assumed that blank periods are provided between 90 and 91 and between 112 and 113, respectively. Thus, 35 sending numbers 1 to 35.31 sending numbers 36 to 66.24
22 sending numbers 91-11
2 and 28 sending numbers 113 to 140 constitute blocks with first to fifth sending numbers, ie, blocks (groups) of tape cassettes (7).

Note that the tape cassette automatic supply selection and playback machine M can be used by, for example, using two (three or more) tape cassette automatic supply selection and playback machines Mx and M2 alternately (circularly if there are three or more). It is sufficient to replace the tape cassettes (7) on the shelves (11) to (1n) of the tape cassette automatic supply selection reproducing machine that is in use and is in a dormant state.

(Then, the number of tape cassettes (7) to be used is 1) on the shelf (11) of the tape cassette automatic supply selection and playback machine M.
When the number of stages (In) is greater than n, the tape cassette (7) can be efficiently and easily allocated to a plurality of tape cassette automatic supply selection and playback machines M1 to Mk.

Also, the tape cassette (7) stored in the shelves (11) to (In) of one or more tape cassette automatic supply selection and playback machines M is read from the barcode (11) of the tape cassette (7). The identification data of 7) is stored in the storage means (25
) and each time the tape cassettes (7) stored in the shelves (lx) to (1n) are replaced, the identification data stored in the storage means (25) is updated. As a result, the blanks in each item of the above-mentioned transmission list are filled in or corrected and displayed on the screen of the monitor receiver (14M).

In the following description, for the sake of simplicity, an example will be explained in which one tape cassette automatic supply selection and playback machine M shown in FIG. 1 is used. Next, the above-mentioned sending list (monitor receiver (
A simple example of what was displayed on the screen of 14M) is shown below (at the time of youth broadcast).

<Table 1> Next, the contents of Table 1 will be explained. Every time there is a blank period between transmission numbers, the channels are changed sequentially from A-B-4C→
It is switched cyclically from D to A.

The VTR is switched to a different VTR each time the transmission number changes, but there is no correspondence between VTR numbers 1 to 4 and channels A to D. However, when the channel is switched, the VT
Switch R as well. Note that although the time or time data actually includes hours, minutes, seconds, and frames, frames are omitted for simplicity.

The dispatch numbers are not necessarily in numerical order; the numbers may be skipped or the order of the numbers may be reversed due to insertion of a dispatch number, etc.

There are cases in which reproduced video signals from tape cassettes with different transmission numbers belonging to different channels are simultaneously reproduced by different VTRs, and the reproduced video signals of one channel are selectively transmitted by the switching means (43) (FIG. 8). The video signals of tape cassettes with adjacent transmission numbers may be reproduced partially overlappingly at the time of transition, and may be faded in or out by the special effect generating device of the switching means (43), for example.

The tape cassette automatic supply selection playback 4aM in Figure 1 is VT.
There are four R units (7) as shown in Table 1 above.
All VTRs (8t) to (84) are used, but some of them are used as spare VTRs, and the remaining three VTs are normally used.
When using R and one of the remaining VTRs breaks down,
Alternatively, the spare VTR can be used when interrupting (inserting) a transmission number.

lHJ Chi, Figure 1 (7) VTR (8t) ~ (84)
is controlled by the main control means (24) (FIG. 5) of the computer (14), as shown in FIG.

For example, if the VTR (84) is designated as a backup VTR, the VTR (84)
TR (81) to (8a) are regular VTRs, and VTR (84) is a spare VTR as storage means (semiconductor memory, non-volatile storage means such as floppy disk)
(50) (Storage means (25) is also stored).

Among the commonly used VTRs (8z) to (83) and (7), for example, when the VTR (8m) breaks down, the control means (24
), the VTR (83) becomes a standby VTR (84).
and this state is stored in the storage means (50) (the storage means (25) can also be used). In addition, when the transmission number is interrupted (inserted), the spare VTR (84) temporarily and continuously becomes the regular VTR, and this state is stored in the storage means (50).
) (storage means (25) is also possible). Furthermore, VTR
Even if all of (81) to (84) are used in a commonly used VTR, this state is the storage means (50) (storage means (25)
(possible).

This storage means (50) (or storage means (25)
)), that is, the usage status of the VTRs (8z) to (84), is stored in the storage means (25) (Fig. 5), and based on this, the VTR item column of the above-mentioned transmission list is filled in. , or amended.

In this way, even if there is a failure in some of the multiple VTRs, the failure can be quickly compensated for by the spare VTR, so the VTR
There is no trace of the transmission of reproduced video signals from the TR.

Further, it is possible to interrupt or add a transmission number to the transmission list, that is, to quickly reproduce the tape cassette on the VTR as the transmission list is changed.

Next, a method for determining the order in which VTRs are used will be explained. Based on the above transmission list, VTR (81) ~(
84), when the playback of the tape cassette (7) loaded in a certain VTR is completed, that tape cassette (7) is
7) is carried by the elevator (2) to the shelves (11) ~
(1n) is returned to its original shelf, and the tape cassette (7) stored in the other shelf is returned to the elevator (2).
and then reloaded into the VTR. By repeating this, shelves (11) to (1n)
The tape cassettes (7) stored in the tape cassettes (7) are sequentially loaded into the VTRs (81) to (84) based on the sending list.
will be played.

In this case, among the VTRs (81) to (84), the earlier the reproduction start time, the higher the priority. Then, the VT
The order in which R is used is determined by calculation by the computer (14). If some of the VTRs (81) to (84) are reserved, the same determination is made for the remaining VTRs.

This will be explained with reference to the functional block diagram of FIG. 12, the flowchart of FIG. 13, and Table 2 shown below.

Table 2 〉 In Figure 12, (25A), (25B), (251
) to (254) indicate some storage areas of the storage means (25) in FIG. 5, and these will also be referred to as storage means. The storage means (25^) stores data on the playback start time and playback end time of the tape cassette of each sending number based on a list as shown in Table 2, for example. The storage means (251) to (254) are connected to the main kVTR (8z) to (
84) Store the reproduction end time of (numbers 1 to 4). The playback end time data read from the storage means (251) to (254) is then supplied to the playback start order determining means (51) of the VTRs (8z) to (84), and is then processed as shown in Table 2, for example. The priority order is given in descending order of the playback end time, and the playback start order of the VTRs (81) to (84) is stored in the storage means (25B), so that the VTR column of the item [phase] in the transmission list is is filled in. If the sending number is inserted or changed, this operation is performed again.

By doing so, it is possible to take enough time to replace and load the tape cassette (7) into the VTRs (81) to (84).

Next, regarding the Teisuke control machine (14K) in Fig. 1, the 14th
This will be explained with reference to the figures. (60A) to (600) are display marks corresponding to channels A to D, (61A) to (
610) are normal playback control operators (operation buttons) for the VTR corresponding to channels A to D, (62A) to (62
D) are still image playback control operators (operation buttons) for the VTR, (63^) to (63D) corresponding to channels A-D.
) are the control buttons (operation buttons) that return the VTR to the playback ready state, which correspond to channels A to D, and (64) are the power switch controls (slide descendants), respectively on the panel (66).
) is placed on top.

To explain the operation of this auxiliary controller (14K), when the power controller (64) is on, the controllers (61^) to (
63D) (also serving as a display element), the control means (24) of the microcomputer (14) is operated.
), the VTR of the corresponding channel
At the same time, the control is turned on. When the operation of the controlled function for the VTR of that channel is completed, the lighting state of that operator is canceled under the control of the control means (24).

In addition, the operators (61A) to (610), (628) to (6
2D), (63A) to (63D) to each channel A.
-D may be used as a common operator, and a separate channel selection operator (also serving as a display element) may be provided.

By employing such an auxiliary controller (14K), in combination with the selection means (41) and the switching means (43), control over the plurality of VTRs (81) to (84) can be performed on channel A.
-D, it becomes easy to control a plurality of VTRs.

Next, the operation of the tape cassette automatic supply selection reproduction machine M which sequentially transmits reproduced video signals from a VTR based on the above-mentioned transmission list will be explained.

Since the sending list is stored in the storage means (25) of the microcomputer (14), the elevator (2) is controlled by the microcomputer (14) accordingly, and the elevator (2) loads the shelves ( 11) - Tape cassette +? from (1n) one by one? ) is taken out, transported to a predetermined VTR among VTRs (8z) to (84), and loaded by horizontal loading. Also, tape cassettes (7) of VTRs that have finished playing
) is removed from the VTR by horizontal unloading,
The elevator (2) returns the items to the original shelves (11) to (1n) or to a previously designated return-only shelf.

While the tape cassette automatic supply selection playback device M is in operation, r PLAYJ is displayed in the playout list on the screen of the monitor receiver (14M) if the corresponding VTR is playing, and rclIE is displayed if the corresponding VTR is in playback preparation state. UPJ is displayed.

Also, multiple tape cassette automatic supply selection playback machines M1 to M
When using tape cassette k, when all the tape cassettes (7) on the shelves (11) to (1n) of the - tape cassette automatic supply selection and playback machine have been played, the tape cassettes (7) on the shelves (11) to (1n) of the playback machine are automatically fed.
A new tape cassette (7) is manually stored in the tape cassette, and the other tape cassette automatic supply selection/playback machine is operated.

Now, while the tape cassette automatic supply selection and playback machine M is operating the tape cassette automatic supply selection playback machine M according to the sending list, it may be necessary to change the sending list. This will be explained below with reference to FIG. 15 showing the functional blocks of the computer (14) and FIG. 16 showing the flowchart thereof.

First, a case will be described in which a tape cassette (7) is already loaded in the VTR and is replaced with another tape cassette (t7). That is, VTR (8z) to (84)
It is assumed that all tape cassettes and throats (7) are loaded. In Figure 15, (70) is a low priority V
When a transmission number insertion command is given to the TR detection means from an input terminal (71), the VTR having the lowest priority at that time is detected. This detected data of the VTR is given to a detection means (72) that detects whether or not the VTR is playing. If it is playing, the detected data is given to the detection means (70).
The VTR with the lowest priority at that time is detected again. If the detection means 111 (72) detects that the VTR detected by the detection means (70) is not playing, the detection data is supplied to the control means (73). The control means (73) controls the elevating drive means (4), and the elevating drive means (4) drives and controls the elevator (2).
) to one of the shelves (11) to (1n), and at the same time take out the tape cassette slot (7) with the desired delivery number from one of the shelves (11) to (In) and load it into the detected VTR. . When it is the detected VTR's turn to play, the tape cassette (7) loaded in that VTR is played.

For example, in Table 2, tape cassette 7H7 with sending number 1)
(7) When the stored VTR (83) (number 3) is playing, the VTR with the lowest priority is transmission number 4.
VTR (82) loaded with tape cassette (7)
) (number 2). If the VTR (82) is not playing, the tape cassette (
7) is replaced, for example, with a tape cassette (7) having the sending number 10 or the sending number 125. Also, the VTR (83) (in which the tape cassette (7) with the sending number 1 is loaded)
If both the VTR (82) (number 2) loaded with the tape cassette (7) with the number 3) and the tape cassette with the feed number 4 are playing, the next VTR with the lowest priority is the tape cassette with the feed number 7. (7) loaded VTR (83)
(No. 3). Therefore, the tape cassette (7) loaded in this VTR (83), for example, has the sending number 10.
Alternatively, it may be replaced with the tape cassette (7) with sending number 125. Note that the tape cassette (7) with the sending number IO is stored in advance on one of the shelves (11) to (in).
The sending order has changed, and the tape cassette (7) with sending number 125 is the tape cassette automatic supply selection reproducing machine M.
is stored in one of the shelves (11) to (In,) after starting the feeding operation (in this case, the shelf is designated and the photodetector (12) of the elevator (2) (7) barcode (11) must be read) or as a spare shelf (11) to (1n) in advance.
).

In this way, when a sending number is inserted, the playback start time of the tape cassette (7) of the subsequent sending number is delayed by the calculation of the control means (24) of the computer (14), and the inserted The revised transmission list including the transmission number section is displayed on the monitor receiver (14M).

Note that a plurality of transmission numbers may be inserted at the same time.

For example, in the case of 2 polarization, VTR (8z) ~ (84
), the tape cassettes (7) loaded in the third and fourth priority VTRs may be replaced with two other tape cassettes (7).

In this way, it is possible to easily and reliably insert a desired transmission number, that is, a reproduction signal from a desired tape cassette (7) into the transmission list.

Note that it is also possible to delete part of the sending list.

Also, during the sending operation of the tape cassette automatic supply selection playback machine M, a blank period (VTR
By inserting a switching period), the channel after the blank period is inserted is changed, different VTRs are played back before and after the blank period, and fade-in, fade-out, etc. are performed during the blank period. enables the generation of special effects. In this case, the channel in which the blank period was inserted and the next channel are taken into consideration, and the channel after the blank period is changed to a channel different from both the channel in which the blank period was inserted and the next channel.

This will be explained below with reference to FIG. 17 showing the functional blocks of the computer (14) and FIG. 18 showing the flowchart thereof.

Reference numeral (80) is a detecting means for detecting a channel in which a blank period has been inserted, and when a blank period insertion command is given to this from an input terminal (81), a channel in which a blank period has been inserted is detected. This channel detection means (8
0), when a channel into which a blank period has been inserted is detected, the detection data is given to the channel detection means (82) for detecting the next channel, and the next channel is detected. Then, the detection data of the both channel detection means (80) and (82) is given to the channel change means (83), and the channel after the blank period of the channel into which the blank period has been inserted is changed to the both channel detection means (80) and (82). ), (82), the channel is changed to a channel other than both channels detected, and is stored in the storage means (25).

In the transmission list of Table 1 above, for example, if a blank period (time is zero) is inserted between transmission numbers l and 2, the channels of transmission numbers 2 and 3 will both change from A to C (or D is also possible). Be changed. However, the channel with transmission number 1 remains A.

In this way, the overall order of channels is not changed, the change in the order of channels is partially stopped, and by inserting a new blank period, other already existing blank periods (especially zero or very small (duration of time) disappears, and there is no longer any possibility that special effects may not occur.

Note that blank periods can also be deleted. In that case,
The channel after the blank period is changed to be the same as the channel before the blank period.

In Table 1 above, if the blank period between transmission numbers 3 and 4 is deleted, the channels of transmission numbers 4 to 6 are changed from B to A. If the blank period between transmission numbers 3 and 4 is zero or a minute time, the generation of special effects will be stopped.

Next, if the elevator (2) in the tape cassette automatic supply selection reproduction fiM fails, the tape cassette (7
) barcode (11) may not be able to be read, so install a barcode reader (manual barcode reader) (85) on the elevator (2) as shown in Figure 19. (It can also be installed separately).

This barcode reader (85) is provided with a photodetector (12') that detects the barcode (11) on the back of the tape cassette throat (7), and a detection signal from this photodetector (12') is provided. is supplied to the above-mentioned microcomputer (14) via the A/D converter (13').

If the elevator (2) breaks down, the tape cassette (7)
on the auxiliary barcode league (85) and manually move the tape cassette (7) back and forth to detect the photodetector (12').
) detection data, that is, the tape cassette throat (7)
The identification data of is stored in the storage means (25) of the microcomputer (14). After that, load this Notef cassette (7) into an empty VTR with a lower priority among VTRs (8t) to (84), and when it is your turn to play back, as in Doriichi, that tape cassette (7) is loaded. That VTR
Play with.

Tape cassette automatic supply selection reproducing machine M according to a pre-made sending list (consisting of sending numbers from 1 to 35, for example)
The operation when the elevator (2) breaks down while the elevator (2) is in operation will be described with reference to FIG. 20, which shows the transmission list displayed on the screen of the monitor receiver (14) 1). The meanings of the symbols for each item and content in FIG. 20 are as follows.

NO: Sending number MD: Mode identification number TTL: Title STT: Tape playback start time DRT: Tape playback time ACT: Tape playback cumulative time M8 cassette supply machine BN: Shelf CH; Channel VT: VTR VTM: VTR mode PLY: Playback Medium CUE + Preparing for playback As shown in Figure 20A, transmission number 15.16 is being played.
Assume that the elevator breaks down while transmission number 17 is in preparation for reproduction. Note that, since there is a possibility that the VTR number may change due to insertion of a transmission number, etc., VTR numbers below the transmission number that is being prepared for playback are not displayed.

As a result, the display in the shelf BN column and the display in the rows with sending numbers 18 and below disappear, and a horizontally elongated frame is displayed below the sending number (17). So, while looking at the hard copy output list, I searched for the tape cassette (7) with output number 18 from the shelf opening () to (in), hung it on the auxiliary barcode league (85), and read the barcode (11). After reading, if you load it into an empty VTR (81) (number 1), each item column except the shelf item will be filled in and displayed in the frame, and then the frame will be displayed as shown in Figure 20C. As shown, the sending number (18)
Move to the next line. In the state shown in FIG. 20C, transmission numbers 16 and 17 are being reproduced, and transmission number 18 is in a reproduction preparation state. From then on, repeat this operation.

In this way, even if the elevator (2) is out of order, the tape cassette (7) can be manually played back and selectively sent out by the VTR.

In addition to the VTR, audio tape recorders, data tape recorders, etc. can also be used as playback devices.

Further, instead of a bar code, identification data may be attached to the back of the tape cassette by magnetic recording or optical recording.

Effects of the Invention According to the present invention described above, a plurality of tape cassette reproduction and transmission numbers and a switching period of a reproduction device are arranged according to a time sequence, and a plurality of tape cassette reproduction and transmission numbers are sequentially assigned before and after the switching period. When a new switching period is inserted between adjacent tape cassette playback and sendout numbers in the playback and sendout list in a device that creates a playback and sendout list for tape cassettes in which playback devices of different channels are specified. , without changing the overall channel order, partially stopping the channel order change, and inserting a new switching period, which eliminates other existing switching periods and creating a special effect. You can obtain something that does not have the risk of becoming impossible to generate.
